SCREEN.

Application filed March 14, 927. Serial No. 175,087.

My invention relatesto improvements in screens for doors, windows, or the like.

The object is to provide a slmple, sturdy, inexpensive screen of the character described, which screen can be cheaply manufactured and which is so constructed that the screen mesh which it carries is so securely held in place as to be capable of withstanding substantially strong blows without being torn loose.

A meritorious feature of my invention lies in the provision of a screen having a wood frame to which the screen cloth is securely fastened without the use of nails or the like and without the employment of the usual molding.

Other objects and advantages of my invention will more fully appear from the following specification, appended claims and ,accompanying drawing, wherein:

, Fig. 1 is an elevation of a screen embodying my invention.

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1 with the filler cord removed.

Fig. 3 is a sectional view taken on the same line as Fig. 2 with the filler cord in place.

Fig. 4 is a fragmentary elevation of a modified form of construction.

Fig. 5 is a sectional view taken on line 55 of Fig. 4.

In the embodiment of my invention illustrated in the drawing the screen frame indicated as 10 is provided with an encircling continuous groove 12 formed in its outer face. This groove is spaced from the inner margin of the frame and is substantially rectangular in cross-section. It extends into the frame angularly toward the inner margm of the frame and its inner side wall therefore forms an acute angle with the outer face of the frame.

The screen mesh or cloth 14 is fastened to the frame by having its marginal portion bent into the groove or channel 12 of the frame. This marginal portion of the nel 15-with its opposite sides closely engaging the opposite side walls of the channel 12 in the frame. The bottom of themesh channel formed by this shaping of its marginal portion snugly abuts the bottom of the chan- ,nel 12 in the frame.

In Figs. 1 to 3 inclusive, I have provided a compressible filler cord 16 which is inserted within the channel 12 of the frame In Figs. 4 and 5 I have illustrated my invention without the employment of the filler cord. The screen mesh at its margin is bent into the channel 12 of the frame and the marginal portion of the screen mesh is shaped into channel form and pressed into the channel of the frame by a tool of such a character that the channel mesh snugly impinges the side walls of the wood channel in the frame.

In my improved screen the screen mesh is so shaped within the channel in the wood frame and the channel in the wood frame is so shaped and positioned that the screen mesh is held securely against being accidentally torn lose. The channel extends inwardly toward the inner margin of the frame and the screen mesh is therefore bent over the sharp corner formed at the inner margin of the channel and is pressed snugly into the side walls of the channel of the wood frame and against the bottom thereof.

Any blow which is struck against the screen mesh and which would ordinarily tear the same loose is resistant not only by the frictional engagement of the screen with the inner side wall of the channel but the channeled portion 15 of the screen is forced against both side walls of the wood channel and the frame, and the engagement therewith is so snug that the screen mesh is held securely against being torn away.

What I claim is:

1. A screen having, in combination, a wooden frame provided with a continuous substantially rectangular encircling channel .formed in one face and spaced from its inner margin, said channel being so arranged as to-extend from said face angularly toward said inner margin, screen mesh secured to the frame by having its margin turned into said channel to engage the opposite side walls thereof, and a compressible filler strip of a width normally greater than said channel wedged into distortion within said chan nel between those opposed portions of screen mesh which abut opposed side walls of the channel.

2. A, screen having, in combination, a wooden frame provided with a groove in one face, said groove extending with substantiall parallel side walls into the frame toward its inner margin and at an acute angle with respect to the plane of the screen secured to the frame, screen mesh secured to the frame by having a portion turned into said groove, said portion being so shaped as to closely engage the opposite side walls of the groove, and means within the groove wedging said screen closely against the op posite parallel side walls of the groove.

3. A screen having, in combination, a wooden frame provided with a groove in one face, said groove being substantially rectangular in cross section and extending into the frame angularly toward its inner margin, and a screen mesh secured to the frame by having a portion turned into the groove,

said portion being bent into channel form closely engaging both side walls and the bottom of the groove and a round flexible compressible cord having a normal diameter greater than the width of the groove pressed into said groove substantially filling the same and Wedging the screen mesh against the bottom and both side walls of the groove.

'4. A screen comprising, in combination, a frame provided with a substantially rectangular continuous groove formed in one face encircling the opening defined by the frame and having an inner side wall forming an acute angle with said face and an outer side wall forming an obtuse angle therewith, and screen mesh secured to said frame ARTHUR T.
